> The current pattern used for extracting tags from the tags field:
>     Pattern tagPattern = Pattern.compile(".*"+tagName+"=\"(.*?)\".*");
> Doesn't work very well. If you pass tagName "bar", will also match (and return) the content of foobar="dssad" tag.
> The proposed path is more correct, and also faster than using .*
